: graffiti tags are popping up daily along alum rock avenue big ones, small ones, dozens on a single doorway. >> makes me feel like a slap in the face because i was born and raised here on the east side and live this place. and i'm sure a lot of other people love it here as well. >> reporter: frank cortez is the president of the alum rock business association. >> this is probably done last night because i didn't see it yesterday. >> reporter: he says this constantly tagged wall was just given a fresh cold front paint in preparation for a new store opening up but it's already been tagged. >> i don't think they realize the large amount of money that gets wasted every year on covering up their graffiti. >> reporter: but it's not just an east side problem or just in san jose. cities all across america are experiencing a bumper crop of graffiti tag this is summer, tagging usually does increase during the time kids are out of school. but this year's increase may also be due to the economy. >> they have nothing else to do for entertainment. a can of spray costs four bucks. they go do what they can.
